Rated 5 out of 5 by from Usable Day One Bought today-will use soon-the hardest part to date is finding where to use the cutter's head locking tool. The little slot is between blade and safety housing on side of cutter head spindle. To remove blade, one must hold spindle tool with one hand and untighten (reverse thread) blade nut with other hand.

Rated 5 out of 5 by from Perfect Just brought the Expand-it Brush Cutter for my old 4 cycle X430, Model RY3400, it had been sitting for many years, not used much. I added the Brush Cutter to it and WOW clear out vines and weeds over 4 feet tall, my old unit was brought back in 2009, and had to replace the gas lines, and bulb, after the unit ran like a new one, and this attachment was perfect to clean up my brush. love it.
